Early-type galaxy density profiles from IllustrisTNG: I. Galaxy correlations and the impact of baryons

Yunchong Wang, Mark Vogelsberger, Dandan Xu +10

We explore the isothermal total density profiles of early-type galaxies (ETGs) in the IllustrisTNG simulation. For the selected 559 ETGs at $z=0$ with stellar mass $10^{10.7}\mat…
